Some help with N45AP.plist

Hey guys,
I'm trying to reorder my icons on the Springboard by editing the N45AP.plist file, but there are some icons-codes missing.
I would love you for giving me the names(codes) for the following applications:
Mail
psx4all
gpSPhone
Lockbox
Sysinfo

Thanks in advance, Lasse.

P.S.: No, I cannot use Customize, because I did this Music-Video-Icons to iPod-Icon thing and since I did this, the reorder-function in Customize does not work anymore.
